Answer 2

Answer:

(D) made mostly out of gas

Explanation:

The temperatures of the early solar system explain why the inferior planets are rocky and the outer planets are gaseous. As the gas fused to the protostar, the temperature of the solar system rose. The temperature of the inner solar system was as high as 2000K, and the temperature of the outer solar system was as low as 50K.
